More and more CDN providers are appearing with competing prices and features. Here I’m going to compare Amazon CloudFront, Rackspace CloudFiles, and Amazon S3.

First off, Amazon S3 isn’t really a CDN per se, but I’ve ran across quite a few sites comparing Rackspace Cloud to S3, which isn’t a fair comparison. Amazon S3 does, however, have its own strong points which we will get into later.
